Asteroid 2007-TU24An asteroid will fly past our own planet on January 29, 2008. At closest approach, 2007 TU24 will be 1.4 lunar distances from Earth. There's no danger of a collision, but the 400m-wide space rock will be close enough to photograph through backyard telescopes as it speeds through the constellation Cassiopeia glowing like a 10th magnitude star.
